FIELD: physics.
SUBSTANCE: use to determine parameters of a fluid mixture. Summary of the invention consists in the fact that a fluid mixture parameter determination (FMPD) system for analysing a fluid mixture during movement includes a computer system and at least one material model, including two or more model parameters for multiple compositions of materials stored in memory. Ultrasonic sensor and a millimetre wave (MMW) sensor, each of which is connected to measure the fluid mixture and is connected to a computer system. Ultrasonic sensor is designed to provide ultrasonic measurement data to the computer system, including the flow rate of the fluid mixture or volumetric flow rate, as well as the speed of sound (VoS) in the fluid mixture. MMW sensor is designed to provide the MMW speed data to the computer system. Computer system is intended for application of material model together with ultrasonic measurement data and MMW rate data for identifying parameters including a plurality of components in the fluid mixture and concentration for the plurality of components.
EFFECT: high reliability of determining parameters of a fluid mixture.
